Hello, I am researching some coins for a friend and he gave me this crown the other day. It comes in a red bespoke plastic case with the dates 1952-1977 written in the top corners.
The thing is, it's supposed to weigh an exact amount and when weighed it comes up a bit short. I think it's the correct size and has the milled edge. I know there is a difference between the jubilee coins but this one feels heavy enough to be silver. Any advise please most welcome.
